Direct fluorometric determination of urea in urine.
Urea in biological fluids has been determined by a variety of direct and indirect procedures. Some indirect methods depend on the hydrolysis of urea with the enzyme urease to form ammonia, with subsequent quantitation of the ammonia by nesslerization (1-4). Undesirable features of these indirect methods are the use of relatively unstable reagents and loss of ammonia during the procedure. Direct...
متن کاملThe Determination of Urea in Urine
The method outlined in the foregoing. paper for the estimation of urea in blood is perfectly reliable for larger quantities of urea (up to 25 mgms. or perhaps more). Its adaptation to the determination of urea in urine using only a small amount of the urine is shown in this paper. The method to be described is slightly more accurate than the rapid clinical method proposed earlier.’ The reason f...
متن کاملEnhancement by Urine of Urinary Bladder Carcinogenesis1
The role of urine as a tumor-enhancing agent in urinary bladder carcinogenesis was investigated by using the heterotopically transplanted rat urinary bladder. Bladders removed from rats initiated with the carcinogen /V-butyl-/V-(4-hydroxybutyl)nitrosamine in drinking water for 4 or 10 weeks were heterotransplanted to syngeneic rats. Those heterotopically transplanted bladders receiving repeated...
متن کاملUrodynamic prognostic factors for large post-void residual urine volume after intravesical injection of onabotulinumtoxinA for overactive bladder
The aim of this study was to identify factors predicting large post-void residual (PVR) (defined as ≥200 mL), an important unsolved problem, after an intravesical injection of onabotulinumtoxinA in patients with overactive bladder syndrome. The data showed that 133 of 290 patients had a large PVR after treatment. Multivariate analysis found that the baseline 3-day daytime frequency episodes and...
متن کاملThe Effect of Urine Volume on Urea Excretion.
In recent papers Bing (1) and Williams (2) have proposed formulae which these authors believe to be more accurate than the original "standard" and "maximum" clearance equations of M6ller, McIntosh, and Van Slyke (3, 4), in expressing the effects of urine volume flow on the urea clearance in human subjects. Both Bing and Williams base their formulae on the data of M6ller et al (3). The essential...
